Question

A diver of mass m drops from a board 16.0 m above the water's surface, as shown in the figure. Neglect air resistance.

Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.95 m/s upward. Use energy conservation to find his speed when he strikes the water.

____________m/s

Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.95 m/s upward. Use energy conservation to find his speed when he strikes the water. ____________m/s

Explanation / Answer

16*9.8+1/2*3.95^2=1/2*v^2 v=(32*9.8+3.95^2)^0.5=18.14 m/s
